Mr Mark (pictured) said he has been doing paranormal investigating for ten years, and the hospital is 'one of the most active places I have been'

‘I have been doing this [paranormal investigating] for ten years now and it’s one of the most active places I have been. That place is really good for this kind of thing as a lot of death occurred there.’

The hospital closed in 2007 and has had security guards working on the derelict site.

Mr Smart said one guard was so scared he had to leave the office inside the disused building and get his boss to give him a caravan to let him sleep in.

He said: ‘A security guard got in touch with me who worked at the hospital when they first closed it. He was on the night shift and he didn’t believe in anything paranormal, ghosts or “any of that rubbish” he said - until he worked there.

‘He said the amount of occasions they had to phone the police and have them do a sweep of the hospital because of the noises, girls screaming and stuff like that. But the police would come in and find nothing.’
